I appreciate the helpful diagnoses made by you and another. As you suggested, I left blank line 41 (inventory on hand at 2020 year end). Let me ask your obviously expert advice about correcting that mistake. I still have the inventory and am using it for 2021 sales. Apparently I should file an amended 2020 return with the $5,536 shown on line 41, thereby eliminating the phantom loss. Am I right?
